Silca Protocol RCG-3 32" Tire Big Wheel Energy Riders running 32-inch wheels have been asking for a gravel tire worthy of the format. The Protocol RCG-3 in 32 x 2. 4 delivers exactly that: the RCG-3's proven mixed-terrain tread scaled to a wheel diameter that simply rolls over obstacles differently than a 700c tire can. The larger diameter creates a shallower angle of attack against rocks, roots, and rough chop, so the energy that would otherwise go into pushing through an obstacle goes into moving forward instead. The Seal Skin puncture layer underneath the tread keeps the casing intact on the kind of rough, unpredictable terrain where this wheel size shines, and the Carbon Bead Lock bead locks the tire dimensionally stable for the life of the rubber. If your frame has the clearance and your course rewards stability and rollover over lowest-possible weight, this is the tire for that setup. Features RCG-3 mixed-terrain tread in 32 x 2. 4 tightly spaced, elongated center knobs grow in size and height toward the shoulder for grip and contact patch through corners on rough, variable surfaces Pulsar Compound high-performance rubber and silica race compound engineered to hold rolling efficiency, grip, and durability in balance without trading one away for another 120 TPI race casing developed around modern tire pressures and wide rim profiles so the tire holds its shape and ride quality at the pressures wide rims actually run Seal Skin Protection Layer under-tread puncture breaker adds flat resistance without the sluggish feel of a conventional heavy-casing protective tire Carbon Bead Lock bead rigid carbon fiber bead eliminates the stretch and moisture retention of Kevlar beads, keeping the tire dimensionally stable and hookless-compatible for its full lifespan Tubeless-ready engineered for modern tubeless systems from the bead out; casing uses a proprietary latex-friendly mold release agent that bonds with sealant rather than repelling it Specifications Size32" (812mm)Width(s)2. 4"Compound Pulsar Compound Casing120 TPI Race Casing with Seal Skin Protection Layer TPI120Bead Carbon Bead Lock (carbon fiber, folding-equivalent rigid bead)Tubeless Compatible Yes (tubeless-ready)Hookless Compatible Yes Weight710g Intended Use Gravel | Silca | Protocol Rcg-3 32" Tire 32X2. 4, Race Casing | Rubber
